端粒沉默1-Like(DOT1L)的破坏者是唯一的组蛋白H3赖氨酸79(H3K79)甲基转移酶,对于白血病的子集进行白血病生成转化时,需要进行混合谱系白血病(MLL)基因的染色体易位以及其他癌症。因此,DOT1L是有吸引力的治疗靶标,小分子抑制剂的发现仍然引起人们的极大兴趣。在此,我们展示了最初由NIH Pilot Scale Library Program主持下生产的1200个核苷类似物的独特聚焦文库的筛选结果。实际上针对DOT1L筛选了完整的核苷组,导致210个推定命中。由于DOT1L抑制剂聚集在两个不同的化学类别中,因此虚拟筛选的体外筛选结果验证了11种化合物的有效性,基于腺苷的抑制剂和缺乏腺苷的新化学型。基于已开发的DOT1L配体结合模型,应用了基于结构的设计策略,并开发了第二代非核苷DOT1L抑制剂。新合成的化合物25是新系列中最有效的DOT1L抑制剂,IC50为1.0μM,与命

molecule inhibitors remain of high interest. Herein, we are presenting screening results for a unique focused library of 1200 nucleoside analogs originally produced under the aegis of the NIH Pilot Scale Library Program. The complete nucleoside set was screened virtually against DOT1L, resulting in 210 putative hits. In vitro screening of the virtual hits resulted in validation of 11 compounds as DOT1L
